1237143-51-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1237143-51-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,7,1,4 and 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1237143-51:
(9*1)+(8*2)+(7*3)+(6*7)+(5*1)+(4*4)+(3*3)+(2*5)+(1*1)=129
129 % 10 = 9
So 1237143-51-9 is a valid CAS Registry Number.
